To all to from it may concern:

Be it known that I, HERMAN C. Pnninn, a citizen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Railroad Cars, of; which the following is a full, clear, concise, and exact description.

My invention relates to railroad carsand has for its general object the provision of improved side bearings. i

In accordance with my invention, side bearings are interposed between the truck and body bolster of a car, each side bearing being adjustable into functioning position by one ofthe bolsters between which it isinterposed when these bolsters are turned *upon their common axis out of the upright plane which they occupy when upon a straight track.

In the preferred embodiment of the in- Vention,ctlie side bearings are mounted upon the truck bolster and are normally clearof the body bolster but so related thereto as to be adjustable thereby into functioning position. These side bearings are desirably in the form of oscillating rollers whichare self restoring. to nonfunctioning position and which are provided with lugs engageable by the body. bolster in order that they may be brought into functioning position. Two such rollers are mounted in symmetrical relation upon eachend of the truck bolster, a portion upon the body bolster being disposed between, :the lugs so that one roller, at each end ofthe truck'bolster, or the Obl1Ql','lS alone brought into functioning position, according to the direction in which the truck and body bolsters are relatively turned. The rollers are desirably made self restoring by being counterweighted in a manner to cause the rollers to return to normal as the body bolster moves away from .the lugs thereof.

The invention will be morefully explained by reference to the accompanying drawings in which Fig. l is a cross sectional view of a portion of a car-body withthe bolsters and a truck beneath the same, portions of the.

truck being shown in section; Fig. 2 is a see tional view on line 2-2 of Fig. 1;'Fig. 3 is.

a cross sectional view on line 33 of Fig. 1; Fig. 4 is a view, similar to Fig. 3, but with the rollers and the bolsters in changed position;-Figs. 5-and6 are sectional Views respectively taken on lines -'55, 6 6 of Fig.

the ears 1' and another roller? is interposed at; Fig. 7 is a perspective view showing a modification of a part of the structure; and

The OllllQh 1 of a car body one n struction is illustrated, though it is under stood that the invention is not to be limited toany particular form of car. Such car body is" provided with two body bolsters one near each end thereof, of which the drawings illustrate but one body bolsterQ. Each body bolster isasseinbled by means of a center bearing 3 with the bolster 4;of a wheel truck. i all except Figs. 7 and 8, the truckbolster i s formed in a castinghaving'upwarclly projecting pairs of ears 4', 4"5, -5 which are arrangedupon chords of a circle whose center is in the axis of the center bearing. d roller 6 is interposed between each pair of between the ears 5 of each remaining pair;

Each roller *bears at its bottomeither upon the liner 8 upon the top wall of the truck bolster, as illustrated, most thoroughly, in

Fig. 8, ordirectly upon the top wall of the truck bolster as'illustrated in Fig. 8. The rollers are formed with arcu'ate surfaces 9' where they engage thetruck bolster and with arcuate surfaces '10 concentric with the arc'u ate surfaces Qthat areto be brought into en gagement with the body bolster when the two bolsters are relatively turned'upon the axis defined by the center bearing. Each .roller'is sufiiciently flattened as, indicatedat '11 to bebrought, at this portion thereof, so

far within the circle of the curved surfaces 9 and 10 asto normally afford a gap 121between such roller and the body bolster, a position which is to obtain when'the two bolsters are in the same upright plane or par allel. sions 12", these extensions in each pairof rollers interleaving, these'cxtensions sufficiently counter-weighting the rollers so that" their upper portions will turn towardeaeh otherin their self restoring adjustment to 11 their normal positions. The top wall of the truck bolsteris formed with an opening 13 at each end thereof into whicht he counterweighting extensions 12 project. Each extension is formed with a'bulge 14 that en-f In the structure. exhibited-in The rollers are formed with extengages one side of the opening 13 to limit the extent to which the rollers may move in their self restoring adjustment. Each roller is formed with a lug 15 and each body bolster has a downwardly continuing portion 16 at each end which is interposed between the lugs 15 of the underlying pair of symmetrically arranged rollers. When the bolsters are in angular relation by being relatively turned out of their normal upright plane, one or the other of the lugs 15 at each side of the car is engaged by the adjacent bolster portion 16,, according to the direction of the relativeturning movement of the bolsters,

whereby the rollers having such engaged lugs are turned to bring their arcuate portions 10 into engagement with the bottom of the body bolster portions 16 whereby the body bolster is then also supported upon the ends of the truck bolster to prevent the car body from sagging when the car is rounding curves. i The rollers are desirably formed with arcuate openings 17 therethrough which receive pins 18 that are carried by the ears 4:, et5, 5. These pins serve to assure the maintenance of the assembly of the rollers with the truck bolster.

Having thus described my invention I claim as new and desire to secure by Letters Patent the following l, The combination with a car truck bolster; of a car body bolster; and oscillating,

rollers interposed between the bolsters and each formed'to support the body bolster, when turned to one position and to be free of this supporting relation when turned to an alternative position and each having a lug engageable with a bolster to be turned thereby to functioning position when the bolsters are angular and each being selfrestoring to non-functioning position when the bolsters are parallel.
